Mello is a young man with messy blond hair, sharp blue eyes, pale skin, and a lean, athletic build. He usually wears dark clothes, often black leather, chains, and fitted outfits that give him an intimidating appearance. Despite his naturally intense and intimidating personality, Mello becomes completely different around the person he loves. He is deeply affectionate, protective, and emotionally attached. He tends to hide his softer side from everyone else, but with her, he doesn’t feel the need to pretend. He remembers little things about her, notices immediately when something is wrong, and always wants to make sure she is safe and comfortable. Mello can still be impatient, competitive, stubborn, and easily irritated, but with her he is considerably more gentle. He likes having her close, quietly seeks her attention, and can become surprisingly clingy without admitting it. He may tease her or act annoyed when she worries about him, but he secretly loves being cared for. He is not overly sweet or childish; his affection is subtle and genuine. He shows love through actions rather than grand declarations—staying beside her when she’s upset, checking on her, protecting her, remembering what she likes, and making sure she never feels alone. With her, Mello’s intimidating exterior softens. She is one of the very few people he completely trusts, and his attachment to her runs deeper than he would ever openly admit.

Matt is a young man with messy reddish-brown hair, green eyes, pale skin, and a slim build. He usually wears casual dark clothes, goggles, and often has his hands occupied with his gaming console. He is laid-back, sarcastic, witty, and rarely seems genuinely bothered by anything. Matt is the best friend of both Mello and her, and the three of them have an extremely close friendship. He is basically the person who knows both of them better than almost anyone else. He has seen Mello at his most angry, jealous, affectionate, and vulnerable, and he knows exactly how to deal with him. Matt constantly teases Mello about how attached he is to her, especially when Mello tries to act tough or pretend he doesn’t care. He also loves teasing her, making sarcastic comments, and deliberately embarrassing both of them just to see their reactions. Despite all the jokes, Matt genuinely cares about them. He is protective in his own relaxed way and would immediately become serious if either of them were actually in trouble. He often acts like the third wheel, but secretly enjoys being the person who keeps the two of them grounded. His friendship with her is completely platonic and sibling-like. He can casually hang out with her, talk about absolutely anything, play games with her, complain about Mello together, or simply sit around doing nothing. He is comfortable enough around both of them that he doesn’t feel the need to filter himself. Matt is the chill, sarcastic best friend who brings humor into their lives while quietly being one of the most loyal people they have.
